In the era of the "Electrification of Everything," the global demand for materials that balance electrical performance with mechanical efficiency has never been higher. C14500 Tellurium Copper (CuTe) stands at the pinnacle of this intersection. Unlike pure electrolytic copper which, despite its high conductivity, presents significant challenges in high-speed precision machining, C14500 is engineered with a small addition of tellurium (0.4% - 0.7%) to revolutionize its machinability rating to 85% (compared to 20% for pure copper) while retaining a minimum of 90% IACS conductivity.
As a leading OEM C14500 Tellurium Copper Bar supplier, Sichuan Kepai New Material Co., Ltd. provides the critical link in the supply chain for New Energy Vehicles (NEV), 5G telecommunications, aerospace propulsion, and high-precision semiconductor components. Our copper solutions are not merely raw materials; they are high-performance engineering catalysts designed to reduce production cycle times and enhance the reliability of end-products in extreme thermal and electrical environments.
Maintaining >90% IACS, our C14500 bars ensure minimal energy loss in power connectors and high-current electrical relays, essential for EV charging efficiency.
Optimized for high-speed automatic screw machines, drastically reducing tool wear and improving surface finish for micro-machined 5G components.
Natural resistance to welding and sticking under electrical arcing, making it the premier choice for contacts and welding torch tips.
Established in 2017, Sichuan Kepai is a high-tech cornerstone enterprise integrating R&D, advanced production, and global sales. Our 9,000 square meter facility in the Sichuan Guanghan Industrial Development Zone serves as a global hub for strategic copper alloy innovation. We focus on materials critical to the "National 13th Five-Year Plan," delivering solutions in Tellurium Copper, Oxygen-Free Copper, Silver Copper, and Dispersion Copper.
Our commitment to innovation-driven development ensures that every millimeter of copper bar we produce meets international standards (ASTM B301, SAE J463), providing our clients with the competitive edge needed in high-frequency and high-load applications.

Our current production utilizes vacuum induction smelting and continuous extrusion processes to eliminate porosity and impurities. This "OFT" (Oxygen-Free Tellurium) variant ensures that the material remains embrittlement-free during high-temperature brazing or hydrogen-environment operations.
The transition toward 6G and ultra-fast NEV charging (800V-1200V architectures) requires copper alloys with even higher thermal stability. Sichuan Kepai is researching "Smart Alloys" with trace additions of zirconium and chromium to further increase softening temperatures above 500°C without sacrificing the free-machining benefits of C14500.
We are also implementing Green Manufacturing protocols, focusing on Tellurium recovery and carbon-neutral smelting processes to meet the EU's Carbon Border Adjustment Mechanism (CBAM) requirements.
Quality is the bedrock of E-E-A-T. Our factory is equipped with world-class machinery to ensure every C14500 bar adheres to the tightest tolerances.
In the North American and European markets, the rollout of ultra-fast charging stations requires connectors that can handle 350kW+ loads. C14500 bars are used for high-current terminals because they prevent thermal runaway and maintain structural integrity during repeated insertion cycles.
The high frequency of 5G signals demands components with zero-defect surface finishes to prevent signal attenuation. The excellent machinability of Kepai’s C14500 allows for the creation of intricate coaxial connectors and wave-guide components with micron-level precision.
Industrial laser cutters in Southeast Asia’s manufacturing hubs rely on our C14500 bars for nozzle production. The material's high thermal conductivity effectively dissipates heat, extending nozzle lifespan by 30-50% compared to standard copper alloys.
Navigating global supply chains requires more than just material supply; it requires compliance certainty. Sichuan Kepai provides full documentation support to ensure your business meets local and international regulations:
